path& remove_filename(); |  | (since C++17)

Removes a single generic-format filename component (as returned by `filename`) from the given generic-format path.

After this function completes, `has_filename` returns false.

### Parameters

### Return value

*this

### Exceptions

May throw implementation-defined exceptions.

### Example

Run this code

    #include <filesystem>
    #include <iostream>
    namespace fs = std::filesystem;

    int main()
    {
        fs::path p;
        std::cout << std::boolalpha
                  << (p = "foo/bar").remove_filename() << '\t' << p.has_filename() << '\n'
                  << (p = "foo/").remove_filename() << '\t' << p.has_filename() << '\n'
                  << (p = "/foo").remove_filename() << '\t' << p.has_filename() << '\n'
                  << (p = "/").remove_filename() << '\t' << p.has_filename() << '\n'
                  << (p = "").remove_filename() << '\t' << p.has_filename() << '\n';
    }

Output:

    "foo/"  false
    "foo/"  false
    "/"     false
    "/"     false
    ""      false
